FREDRIU O. WEIR, OF CINCINNATI, OHIO.

RAI LROAD-FROG.

SPECIFICATION forming part of Letters Patent No. 249,708, dated November15, 1881.

Application filed September 12, 1881. (No model.)

To all 'whom it may concern Be it known that I, FREDRIG C. VIR, ofCincinnati, Hamilton county, State of Ohio, have invented an Improvementin Railroad- Frogs, of which the following is a specification.

My invention relates to the class of frogs made by the bending of theoverlapping ends ct' the rails themselves and thejunction of the samewith the central rails constituting the point by rivets or bolts throughseparatingpieces; and my invention consists in a new methodoi'constructing the separating, spacing, and joining or filling platesnecessarily used between the rails forming the point and the wing rails.

In the accompanying drawings, Figure lis a' plan of' a frog embodying myimprovements; Fig. 2, a cross-section on line x w; Fig. 3, a sideelevation of one of my improved separating, spacing, and joining orfilling plates; Fig. 4, a plan of same. Fig. 5 is a perspective view ofone of the iilling-blocks. Fig. 6 is a modified form of uniting the endsof the spacingplates.

' A A are the outer or wing rails oi' the frog, and B B are the tworails which compose the acute angle or point.

In place ot'lling in solidly between the webs sidewise and the heads andflanges vertically, lconstruct my spacing or iilling plates of severalpieces, preferably four, longitudinally one on each side ofthepoint-rails, at both top and bottom, leaving sufficient space betweenthem for the bolts to be passed, and thus avoid the expensive process ofdrilling holes through them. The ends of these top and bottom plates arebrought together and secured by bolts or rivets, thus closing the endsof the slots and forming shoulders thereat.

The longitudinal movement of the rails is,

prevented by the transverse bolts bearing against' the shoulders thusformed, and the lilling-pieces occupying the spaces between the bolts.

This style ol' construction permits the use of the top filling-plates oisteel, and thereby greatlyincreases the durability ofthe frog when theflanges ofthe passing wheels comein contact and partially rest on thesteel top 'rillingpieces described.

Instead ot secui ing the separating-plates at the ends by rivets orbolts to prevent longitudinal movement, one plate may be bent at theends sufficiently to pass past the end of the other plate, at the sametime forming a shoulder for the transverse bolts; or they may be weldedtogether and accomplish the same purpose.

Having thus described my invention, what I claim is- 1. A frogconstructed of the usual sections of wing and point rails, which arespaced or held apart by spacing-plates located on each side of thepoint-rails and between the flanges and heads of the rails, and formingparallel slots or mortises for the transverse bolts.

2. In a railway-frog, the separating and spacing supporting-platescomposed of two or more pieces united so as to form a continuous mortiseor opening through which pass the transverse tie-bolts which secure theparts together.

In testimony whereofI have hereunto set my hand in the presence of twosubscribing witnesses.
